HOW IT WORKS
Every aesthetic machine relies on one or more of these energy mechanisms.
01
Photons at specific wavelengths absorbed by chromophores (melanin, hemoglobin, water) for selective tissue heating.
02
Alternating current (1–10 MHz) causes molecular friction, generating controlled heat that contracts collagen and stimulates new growth.
03
Mechanical sound waves (20kHz–10MHz) for thermal coagulation (HIFU), fat disruption (cavitation), or product delivery.
04
Direct/pulsed current stimulates muscles (EMS), opens cell membranes (electroporation), or drives ions into skin (galvanic).

Take the QuizFAQ
IPL emits broad-spectrum light (500–1200nm) — versatile but less targeted. Laser emits a single precise wavelength optimized for a specific chromophore. Lasers are more powerful and efficient for permanent results; IPL is more affordable for home devices.
